He has Coach Sonnen coach Jamie Huey on every week along with contestants from the show (this week was Zac Cummings, last week was Jimmy Quinlan & Luke Barnatt). They're all suprisingly candid with us and have told us a lot of interesting tidbits like:

A good amount of Team Sonnen including Barnatt, Quinlan, and Hall are actually in Oregon right now training with Chael

Uriah Hall's favorite fighter is Jon Jones, and felt uncomfortable often times not wanting to be seen saying anything bad about him or his team on camera

Uriah was actually sick the night they went to Hooters. Thus, him being on his own not drinking, being with the guys may have been perpetuated by the show

..and a lot more. I hate to put a plug out but it's a real fun show that you should check out if you're watching

Chael is an amazing coach and a also really good at the mind part of the game, Jone Jones is just like any other fighter that relies on physical attributes, not as good at coaching as he is at fighting.
